I had this problem to once, after restart it works again and others also had this problem. Someone fixed it by disassembling the device and was about LCD ribbon that cause this behaviour. Bad quality control as it seems to be and shame on Samsung.
Send it back and replace it if possible, or for repairs and if want to fix it you self:

I had this problem but after rooting my device, so I did re-flashing with stock rom and everything went normal.
I think it is a software not a hardware error. I had this problem with nearly all Samsung tablets (p-1000, p6200, 7500 and lately with the note 10.1_2014)
and every time I did re-flashing with stock rom and everything went normal.

Thanks a lot for your help.
Some body told me this software problem and others told hardware and I must replace the screen.
I am writing now from my device which had this problem, i bought the phone from KSA from 2 weeks ago and from the first day of use it made restart about 10th time per day until appear this problem, so I'll try to send it to Samsung office their.
I hope they can solve this problem or replace it.
